Dual CAN PCIe Card for Industrial, Automotive Applications
Cervoz Technology, a supplier of embedded components for the industrial PC market, has extended its industrial modular expansion cards line with the MEC-CAN-2802i, which provides two isolated CAN CC (Classical CAN) interfaces. The expansion card delivers a cost-effective solution for integrating CAN CC ports into embedded computer systems, especially in hostile environments. The board incorporates an M.2 [...]
Dual-Channel Linear Actuator Control Module with ESP32
As part of a customer project, I, with the help of a capable hardware designer, developed an embedded system to control two linear actuators, specifically the Thomson Electrac HD model with SAE J1939 interface. The Electrac series of actuators supports two higher-layer protocols (HLP) based on Controller Area Network (CAN): CANopen, and SAE J1939. CANopen is [...]
Automotive Development Module has CAN FD, LIN, Ethernet Port
Renesas has launched a software development board featuring the R-Car S4 System-on-Chip (SoC). The scope of delivery includes the Whitebox SDK open-source software. The R-Car S4 facilitates the launch of Car Server/CoGW with high performance, high-speed networking, high security, and high functional safety levels required as E/E architectures grow into domains and zones. The R-Car S4 solution [...]
Industrial Strength Dual CAN FD Interface in Mini PCIe Form
The VL-MPEu-C1 module by Versalogic, compliant with the Mini PCIe format, is a tiny and rugged dual-channel CAN Bus add-on interface. It supports CAN-FD for high-speed data transfer but is still fully compatible with CAN 2.0 A and CAN 2.0 B (Classical CAN). It supports additional CAN functions, including message acceptance filtering, listen-only mode, and wake-up [...]
Micro CANopen Libraries for Embedded CANopen and CANopen FD
Embedded Systems Academy (EmSA) announced the release of its Micro CANopen libraries as Open-CMSIS-Pack compliant with the Common Microcontroller Software Interface Standard (CMSIS) by ARM. The release simplifies CANopen implementation in embedded systems. Previously, the Micro CANopen libraries were part of selected NXP MCUXpresso software development kits (SDKs). Along with NXP's recent support release for MS [...]
Arduino Uno R4 Combines CAN Bus Port with IoT Capabilities
The Arduino UNO R4 WiFi combines the RA4M1 microprocessor from Renesas with the ESP32-S3 from Espressif, forming an all-in-one tool for engineers with improved processing power and a diverse array of new peripherals. With built-in Wi-Fi and Bluetooth abilities, the UNO R4 WiFi allows makers to launch into unlimited innovative opportunities. Likewise, this universal board boasts a [...]
Know OBD2 Before You Start That Development Project
We at Copperhill Technologies offer a variety of CAN (Controller Area Network) devices for developing automotive and industrial embedded systems. In that capacity, we receive frequent inquiries regarding OBD2 (Onboard Diagnostics). OBD2, or Onboard Diagnostics Second Generation, is a vehicle diagnosis system found in modern cars and trucks. The OBD2 system collects data from sensors and [...]

SAE J1939 250k/500k Baudrate Converter with Arduino Due
The introduction of 500 Kbps (see SAE J1939/14) as an alternative to 250 Kbps, required clarifications on how to solve problems that come with incorporating devices supporting different baud rate settings in the same network. One solution comes with automatic baud rate detection. The SAE J1939/16 document outlines the methods used to detect the baud rate [...]
Programming Thomson Electrac Linear Actuator - Sleep Mode
This post represents an excerpt of Thomson Electrac HD Linear Actuator Motion Control per CAN Bus. The application note is available in eBook and Kindle format, and it includes a free downloadable source code. More Information... In this post, I am explaining the actuator's sleep mode, which, if not fully understood, may cause some headache during the development [...]
